[0022] The invention provides a preparation method of mineralized plant nutrient solution, comprising the following steps:
[0023] (1) mica stone, vermiculite and sulfuric acid solution are mixed, carry out acidification reaction, obtain acidification reaction liquid, during described acidification reaction, sulfuric acid solution is excessive;
[0024] (2) Mixing the acidification reaction solution with Sulfolobus acidocaldarius to carry out a free acid passivation reaction, and obtain a mineralized plant nutrient solution after solid-liquid separation.
[0025] The invention mixes mica stone, vermiculite and sulfuric acid solution to carry out acidification reaction to obtain acidification reaction liquid, and the sulfuric acid solution is excessive during the acidification reaction. The present invention has no special requirements on the sources of the mica stone and vermiculite, and the commercially available mica stone and vermiculite in the field can be used. In the p...
Embodiment 1
[0041] (1) Mix the mica stone with a particle size of 200 mesh and the vermiculite with a particle size of 200 mesh according to a mass ratio of 3:2, add a sulfuric acid solution with a concentration of 10 wt% twice the mass of the mixed raw material, and acidify at 80 ° C for 24 hours to obtain The acidification reaction solution was stirred once every 2 hours during the acidification process, the time for a single stirring was 30 minutes, and the rotation speed was 60 rpm.
[0042] (2) Add Sulfolobus acidocaldarius with a liquid quality of 1‰ to the acidification reaction solution, stir at 40 rpm at 30°C for 4 hours, and press filter through the frame to obtain a mineralized plant nutrient solution , The obtained solid slag is used as fertilizer after being mixed with organic fertilizer.
[0043] After diluting the obtained mineralized plant nutrient solution to 2% with distilled water, the content of each element was detected, and the obtained results are shown in Table 1. ...
Embodiment 2
[0047] (1) Mix mica stone with a particle diameter of 250 mesh and vermiculite with a particle diameter of 200 mesh according to a mass ratio of 3:2, add a sulfuric acid solution with a concentration of 2.5 times the mass of the mixed raw material and be 12wt% sulfuric acid solution, and acidify at 60°C for 20h to obtain The acidification reaction solution was stirred once every 2.5 hours during the acidification process, the time for a single stirring was 35 minutes, and the rotation speed was 70 rpm.
[0048] (2) Add Sulfolobus acidocaldarius with a liquid quality of 1.5‰ to the acidification reaction solution, stir at a rate of 35 rpm at 30°C for 5 hours, and filter through a box to obtain a liquid that is a mineralized plant nutrient solution , The obtained solid slag is used as fertilizer after being mixed with organic fertilizer.
[0049] After the obtained mineralized plant nutrient solution was diluted to 3% with distilled water, the content of each element was detecte...
